I bought a crate ZZ3 engine, complete, carb to pan. The engine has 1,600 miles on it. It was bought in 1996 and has either sat in the crate or in the car for over 10 years. The friend that I bought the engine from lost interest in the car, offered to sell it to me, but I did not have the room for another car! So, I told another friend about the car and he bought it. He is a huge big-block Chevy guy, has several of them sitting around. He decided to put a big-block in the car and sold the engine to me. As I said, it has been sitting for over 16 years. As far as I know, when he drove the car home, after purchasing it, that was the first time the car had run in two years. So, being 16 years old I know the carb it not set up for today's gas. Here are the engine specs:

I would like a recipe recommendation for rebuilding the carb for today's fuel.
